Abstract
An ink-jet recording device in which the pressurized ink is supplied from a single source of pressurized ink to an ink manifold with one inlet port and a plurality of outlet ports each of which is connected to one end of a flexible pipe the other end of which is connected to an ink emission head, whereby the pressurized ink is supplied from the ink manifold to the ink emission head. The ink manifold is hollow and the inlet and outlet ports are communicated with each other through the hollow space. Alternatively, inserted into the ink manifold is an ink distributor having a plurality of branches which are in alignment with said outlet ports and are spaced apart from each other. An ink flow control means is disposed in each branch. The ink manifold is provided with a common ink passage or chamber which is communicated with an air vent means so that air bubbles trapped in the ink passage or chamber may be vented.
